Major Features
Unalloyed Titanium. Relatively low strength, high ductility and excellent weldability. Highly corrosion resistant in oxidizing and mildly reducing environments, including chlorides. Main use in heat exchangers
Unalloyed Titanium. Most widely used titanium in all product forms for industrial use, offering an excellent balance of moderate strength, ductility and weldability. Medium oxygen. Used in piping systems and heat exchanger tubing
Unalloyed Titanium. Offers optimum ductility and cold formability with useful strength, high-impact toughness, and excellent weldability. Highly corrosion resistant in oxidizing and mildly reducing environments, including chlorides. Main use in shell and tube heat exchangers.
The highest strength pure unalloyed Titanium. High oxygen, extra high strength. Good corrosion resistance in neutral to oxidizing environments, including chlorides. Used in hydraulic and instrumentation tubing.
Titanium alloy. 6% aluminium, 4% vanadium. Grade 5 is the most widely used titanium alloy. It has very high strength but relatively low ductility. The main application of this alloy is in aircraft and spacecraft. Offshore use is growing. The alloy is weldable and can be precipitation hardened.
Titanium Alloy. Useful for applications requiring good weldability, stability and strength at elevated temperatures, such as airframe and jet engines.
Unalloyed Titanium plus 0.12% to 0.25% palladium. Medium strength, standard oxygen. Most corrosion-resistant titanium alloy in reducing and oxidizing environments, with a good balance of moderate strength, reasonable ductility and excellent weldability. Physical and mechanical properties equivalent to Grade 2.
Titanium alloy including 3% aluminium and 2.5% vanadium. Also known as "half 6-4". 20-50% higher strength than C.P. grades, but has better weldability and higher tensile strength than the strongest unalloyed grade. Usual applications found in Aerospace, petrochemical, hydraulic & instrumentation tubing, sports and subsea applications.
Unalloyed Titanium plus 0.12% to 0.25% palladium. This alloy is the same as Grade 1, but with palladium added for better corrosion resistance. Low oxygen. Low strength. Especially suitable for deep drawing requiring optimum ductiility and cold formability. Also has excellent weldability.
Titanium alloy including 0.3% molybdenum, 0.8% nickel. High strength. Good heat, wear and corrosion resistance. Used for shell and heat exchangers, hydrometallurgical applications
Titanium alloy including 0.5% nickel and 0.05% ruthenium. Low oxygen.
Titanium alloy including 0.5% nickel and 0.05% ruthenium. Standard oxygen.
Titanium alloy including 0.5% nickel and 0.05% ruthenium. Medium oxygen.
Unalloyed Titanium plus 0.04% to 0.08% palladium. Standard oxygen, medium strength. Has a good balance of moderate strength, reasonable ductility and excellent weldability. Used in chemical industries because of its outstanding corrosion resistance.
Unalloyed Titanium plus 0.04% to 0.08% palladium. This alloy is the same as Grade 1, but with palladium added for better corrosion resistance. Grade 17 has optimum ductility and cold formability with useful strength, high-impact toughness, and excellent weldability. Very resistant to crevice corrosion
Titanium alloy including 3% aluminium, 2.5% vanadium plus 0.04% to 0.08% palladium.
Titanium alloy including 3% aluminium, 8% vanadium, 6% chromium, 4% zirconium, 4% molybdenum. This metastable-beta alloy is strip - producible and cold-formable. The alloy is age-hardenable to a wide range of strengths. The alloy has superior resistance to general corrosion pitting - crevice - and stress.
Titanium alloy including 3% aluminium, 8% vanadium, 6% chromium, 4% zirconium, 4% molybdenum plus 0.04% to 0.08% palladium. Beta - 21S is a metastable beta alloy that offers high specific strength and good formability, and has been designed for improved oxidation resistance, elevated temperature strength, creep resistance and thermal stability, especially in applications above 300°C.
Titanium alloy including 15% molybdenum, 3% aluminium, 2.7% niobium, 0.25% silicon.
Titanium alloy including 6% aluminium, 4% vanadium, and extra low interstitial, ELI23 Alloy 23 is an alpha-beta alloy based on Grade 5, providing improved stress corrosion cracking properties in seawater. Especially suited for thick wall highly stressed parts.
Titanium alloy including 6% aluminium, 4% vanadium plus 0.04% to 0.08% palladium
Titanium alloy including 6% aluminium, 4% vanadium plus 0.3% to 0.6% nickel, 0.04% to 0.08% palladium
Unalloyed Titanium plus 0.08% to 0.14% ruthenium. Standard oxygen, medium strength. A corrosion-resistant titanium alloy offering outstanding resistance to general and localised crevice corrosion in a wide range of oxidizing and reducing acid environments including chlorides. Has a good balance of moderate strength, reasonable ductility and excellent weldability. Mechanical properties similar to Grade 2, but improved corrosion resistance. A competitive alternative to 7.
Unalloyed Titanium plus 0.08% to 0.14% ruthenium. Low oxygen, low strength, and is the same as Grade 1, but with Ruthenium for better corrosion resistance, Grade 27 has optimum ductility and cold formability with useful strength, high-impact toughness, and excellent weldability. Very resistant to crevice corrosion
Titanium alloy including 3% aluminium, 2.5% vanadium, plus 0.08% to 0.14% ruthenium. High strength with enhanced corrosion alternative to 9.
